Hi, I have the same issue with my iPhone 7 Plus, when I purchased it, it was perfect with charge and battery, but one night it was fully discharged since my cable was not working to recharge my phone and it went off and I just tried to turn it on to take a number but at the time it asked for code, it went off again, and since that I leave it with 100% charge at bed time and after almost 7 hours with all apps turned of including wifi & 3G, I get with with only 40% charge and that also sinks like in minutes if I start using my phone. any idea if my batter is no longer healthy??

Thanks.

I can just rephrase...i have that problem as well...no **** idea why it's happening....i tried so many ways, that i'm slowly loosing a point where I started and see no light in the end of the tunnel.

This is literally **** and by that I mean deep ****...so grab your advisory board dear @apple and sit down, cause your sale figures may look stable just until the very moment this portion of unreliability pour over the top of a glass...

I'am wondering about one thing...it's not that Apple users have to hassle through internet like jerks in matter of searching for answer for a creepy situation like this, BUT, if ever Android users have been facing **** that sticky, as we do...and please Apple...have been using your products since ever...BUT..and please read this....that does not implicate, I have no brain and wallet dangerously close to explosion caused by Ben Franklin not fitting in...JUST keep Steve Legacy...and if building a **** **** big "campus" or whatever that is, should help You...ok...go ahead...build patiently two of them...peace

Same here. Battery used to last a LOT before 10.3.3. On 10.3.2 used to last over a day with constant use.

After 10.3.3 same as you describe: draining battery even on airplane mode and overheating.

Awful for a brand new phone and the most recent iOS... 😠

EDIT: I use Facebook app and yes, it does use a lot of resources. But it was fine BEFORE 10.3.3!!

It has always used lots of resources in all versions of iOS.

Also check your battery capacity, make sure it's in good health, you can use Battery Life to check: Battery Life: https://itunes.apple.com/us/app/battery-life-check-devices-runtimes/id1080930585 ?mt=8

Same problem here. Ios 11.2, iPhone 7 Plus bought in September of this year(2017). Go to sleep with 100% turn all com off, turn airplane mode on and battery drainage in excess of 10%.

Just delete it and see if the problem is resolved.

Numerous people I know have had battery drain issues both on iPhones and Androids, delete this app usually resolves these issues.

Facebook is still accessible via www.facebook.com

I've been holding off on Uodating my iPhone 7 to 10.3.3 basically because I'm having laptop problems and always update through iTunes. I finally set it to update via WiFi. I've had nothing but issues with battery since then. My phone is 8 months old and this is ridiculous. For three days since I've updated iOS, my battery drains 10-20% within a few hours with light texting. I used to go to bed at 100% and wake up at 100% or maybe 99%. I'm now waking up to 85%. Looking through settings; nothing was turned on that wasn't prior to update. I even turned more things off. Basically, my very expensive phone doesn't take advantage of the great things Apple claims this can do as I have almost everything turned off to save battery.

Anyone know if updating iOS via WiFi when you receive the note on the phone is any different from physically hooking it up

To a computer and updating via iTunes? I've found forum after forum on this battery issue. I'm typing really only for Apple to see there is another person with the problem so they can resolve.

Yes. I'm having the battery drain issue since I bought iphone 7 plus a few days ago On the first day I had my phone, I power off the phone after 100% charge before noon. 5 hours later, i touched the phone and noted that it was hot. To my horror, the battery drained to 35%. Nothing was activated. Bluetooth, background refresh, wifi, mobile data, location were not on. I also did not install the Facebook app. This is ridiculous! I went to the Apple Approved repair centre. They said there is nothing wrong with the battery and hardware. Probably it is the software which was giving the problem. Hence,they did a reformat on my phone. there is no improvement at all. I'm gonna visit the Apple repair centre again and see what they have to say. I'm very upset about it!

I thought your problem was with your iPhone, not Mac?

Are you using Facebook app?

If so delete it and instead use Facebook on Safari (www.facebook.com).

Facebook app uses a lot of resources!

Hi

Go to settings turn off apps refresh to save battery.

Cheers
